Trump welcomed the Penguins into the Oval Office on Tuesday. He celebrated their second consecutive championship in the East Room of the White House and singled out the achievements of playoff MVP Sidney Crosby, Evgeni Malkin and American Phil Kessel, among others.

Trump has grabbed a number of sports headlines in recent weeks, including his criticism of NFL players for kneeling during the national anthem and his decision to disinvite the NBA champion Golden State Warriors to the White House.

He joked that Penguins co-owner Ron Burkle should help him renegotiate NAFTA but avoided any talk about other sports. The Penguins are the fourth championship team and third pro team to visit Trump at the White House after the NFL's New England Patriots, Major League Baseball's Chicago Cubs and college football's Clemson Tigers.

Trump: NFL Should 'Not Allow People to Kneel' During Anthem

The President defended his tweets regarding NFL players kneeling during the national anthem over the weekend, saying criticism that the issue distracted him from the humanitarian crisis in Puerto Rico was unfair.

Crosby, coach Mike Sullivan and other members of the Penguins said the visit had nothing to do with politics. The team said it respected the tradition of visiting the White House.

Sullivan said after the ceremony that he wouldn't mind if one of his players took a knee during the national anthem.

Tampa Bay Lightning forward J.T. Brown, one of 18 black players in the NHL, became the first hockey player to engage in an anthem protest when he raised his fist while standing on the bench before a game Saturday night.

Trump has called on NFL owners to fire players who don't stand for the anthem and urged fans to boycott games in a series of tweets. He tweeted that he instructed Vice President Mike Pence to leave a game between the San Francisco 49ers and Indianapolis Colts on Sunday if there were any anthem protests, which Pence did. Hours before the Penguins visit, Trump tweeted that tax law should be changed to punish the NFL over the anthem protests.

NHL Commissioner Gary Bettman told The Associated Press recently that said he respects players' views on political and social issues and "people are going to have to decide what makes them comfortable." Bettman said social issues "are a matter of individual belief and individual choice."

In an early morning tweet, Trump said the NFL doesn't deserve tax breaks while it allows players to kneel for the national anthem.

"Why is the NFL getting massive tax breaks while at the same time disrespecting our Anthem, Flag and Country? Change tax law!" Trump said.

It's unlikely that Trump's proposal would change anything. The NFL gave up its federal tax-exempt status a couple years ago and now files tax returns as a taxable entity.

It's his latest missive against the league, roiled by the protests against police brutality and the president's attacks on those protests, in which players sit or kneel during the playing of the anthem.
